Title: Fiber placement compaction preheat system
Inventor: JOHNSON JOHN A
IPC: B29C35/04
Filed: 1991-12-06
Abstract: FIBER PLACEMENT COMPACTION PREHEAT SYSTEM                 ABSTRACT OF THE DISCLOSURE    A compaction preheat system consists of an air heater placed just prior to the compaction roller of the fiber placement head.  The amount of heat supplied to the composite is determined by a control computer.  The controlling computer adjusts the amount of heat being put into the composite by scrutinizing the entire fiber placement process.  The amount of preheat needed is determined by the speed of the fiber delivery, type of fiber being used, amount of consolidation desired, and actual temperature of fiber as measured, e.g., by infrared thermometry.

Title: Miniature electromagnet assembly and relay with the miniature electromagnet assembly
Inventor: KAJI NORIMASA
IPC: H01H50/24
Filed: 1991-12-23
Abstract: A miniaturized electromagnet has an enhanced armature attraction force and reliable armature movement.  The electromagnet comprises an L-shaped flat magnetic plate of magnetic material with a horizontally extending core and a first yoke leg depending from one end of the core.  An excitation coil is wound around the core.  A second yoke member is separately formed from the magnetic plate into a plate configuration and is coupled secured at its upper end to the other end of the core so as to depend therefrom in an opposed relation to the first yoke leg.  The lower end portion of the second yoke leg is bent toward the first yoke leg to define thereat a pole plate extending in parallel with the core. An armature extends in a parallel relation to the core and is magnetically coupled at its one end to the first yoke leg and is pivotally supported adjacent thereto such that the armature is pivotable within a horizontal plane between set and reset positions of having the pole end attracted to and spaced away from the second yoke leg in response to the energization and deenergization of the excitation coil, respectively.  With the provision of the pole plate extending toward the first yoke leg, the armature can be made to have a correspondingly reduced effective length and equivalent mass, whereby the armature can have an increased magnetically attraction force for reliable electromagnetic operation.

Title: Method for injecting wood-preservative liquid into a wooden member
Inventor: VEILLEUX MAURICE
IPC: B27K3/08
Filed: 1992-02-21
Abstract: ABSTRACT     A method for injecting wood-preservative liquid into a wooden member that comprises placing the wooden member in a sealable treatment chamber, and immersing this member in wood-preservative liquid, with the proviso that at least 1% of the volume of the chamber is free from wood-preservative liquid but contains a compressible gaseous substance. The pressure inside the chamber is raised to cause compression of the gaseous substance and a flow of pressurized wood-preservative liquid on the surface of the wooden member, and the pressure inside the chamber is subsequently reduced to cause expansion of the gaseous substance and again a flow of pressurized wood-preservative liquid on the surface of the wooden member. The two latter steps can be repeated at will to improve penetration of the liquid in the wood. After the treatment is completed, the atmospheric pressure is restored in the treatment chamber, the wood-preservative liquid is withdrawn and the treated wooden member recovered.

Patent CA-2064887-A1 (CA)
Inventor: KARAGUEUZIAN HRAYR S
IPC: A61N1/39
Filed: 1991-06-06
Abstract: ECG signals are received from the patient (102), processed (103) to determine deviations from the normal and displayed (104) either as a frequency transformed signal or as a graph of the signal against one of its derivatives in a phase plane plot. The results, depending on the signal and circumstances may be interpreted to obtain information about heart disorders, the degree of drug toxicity or the efficacy of a particular drug. Further, an automatic defibrillator uses the ECG signal received (703) from the patient and processes (704) processing to determine the amount of energy to be discharged into the heart by the shock device (705).

Title: Solid state static power transfer mechanism
Inventor: KEEFE JOHN
IPC: H02J9/06
Filed: 1992-04-23
Abstract: SOLID STATE STATIC POWER TRANSFER MECHANISM          Abstract of the Disclosure A solid state, static power supply control mechanism for coordinated transfer of a load from a pre-ferred source of AC power to an alternate source of AC power should the level of power transmitted from the pre-ferred source fall below a set, adjustable level and thereafter, upon re-establishment of the proper level of operating power of the preferred source, re-transfer of the load from the alternate source to the preferred source.          A unique method of current interlock prevents the alternate power source from connecting to the load until the current from the preferred source is absolutely interrupted, with the same criteria required for re-transfer from the alter-nate to the preferred source of power.  This mechanism and associated switching technique insures supply of power to the load regardless of the preferred power source failure mode and regardless of the phase relation of the preferred and alternate sources of power.

Abstract: Disclosed is a computer audio interface having stereo and filtered sound effects to enable blind users to operate a graphical user interface.  Stereo balance and incremental filtering are used along separate axes to guide a blind or visually impaired user within an area of a graphical user interface, particularly the client area of a window.  As the pointer approaches the left boundary of the client area, the sounds  representing  the  client  area  come  more  and more exclusively from the  left audio channel.   Likewise,  when approaching the  right boundary,  the  sound shifts to the right channel.  Additionally, as the pointer is moved toward the top of the window client area, the pitch of the sound increases in stepwise fashion.

Title: Electronic combination lock with high security features
Inventor: DAWSON GERALD L
IPC: E05B37/00
Filed: 1992-06-18
Abstract: ABSTRACT           An electronic combination lock having a self contained power generation capability is further rendered more secure from attempts to open the lock by an unauthorized individual by requiring the checking the conditions of the lock operation against preset requirements so that if the lock is operated in a manner that indicates that the lock is being operated by a manipulator of if the lock is being randomly operated by a person, the lock will refuse to open or becomes inoperable. Conditions that may be checked by the lock and compared to preset standards include:   entry of the combination is too short a period of time, the entry of the combination over too long a period of time, the amount of the turn of the dial between stops of the dial, the requirement that the dial remain motionless for a predetermined period of time when the dial  is reversed, counting the number of failed attempts to open the lock and signaling an error when a predetermined number is equaled or exceeded, the detection of a dial reversal and the backing up of the displayed number by a set amount to allow the combination number to be approached again without aborting the dialing sequence,  counting  the  number  of  erroneous  attempts  and displaying that number to the operator when the lock is properly actuated and the counting of the number of times that the lock has been properly opened and displaying that number upon the proper operation of the lock.   These features enhance the security provided by the lock itself.

IPC: H04R19/00
Filed: 1992-10-21
Abstract: An electret transducer array and fabrication technique are disclosed. The array comprises a foil having a layer of insulating material and a layer of metal in contact therewith. The layer of metal comprises one or more discrete areas ofmetal which define the active areas of one or more transducers in the array. Electrical leads are coupled to the discrete areas of metal. By means of these leads, electrical signals produced by each transducer in response to incident acoustic signals may be accessed. The areas of metal may be formed by selectively removing metal from the foil, or by selective metal deposition. The layer of insulating material is electrostatically charged. The electret transducer array further comprises a porous backplate of sintered metal. The backplate further comprises a rough surface in contact with the layer of insulating material. The backplate serves as a common electrode for transducers of the array. A second backplate is provided positioned adjacent to the metal layer of the foil forming an air gap therewith. The second backplate provides, among other things, shielding from stray electromagnetic fields.
